This is how the text is structured (excerpt)

The Commentary 147
1. The exposition of the root verses 147
2. The meaning of the title 147
2. The homage of the translator 150
2. The text itself 151
3. An examination and establishment of the two truths 151
4. The two truths identified 151
5. A demonstration that no entities exist on the ultimate level 151
6. The main argument of the Madhyamakalankara (stanza I) 151
7. An investigation of the subject of the probative argument 152
7. An investigation of the argument 153
8. A Prasangika or a Svatantrika argument? 153

You may think this isn't so bad, but this goes on for a few levels more, especially in the
first part of the book. Sometimes this reaches a depth of 21 levels. That
would mean that using more regular numbering you would get sections like
1.2.1.2.2.2.1.1.2, and worse.

I wrote a little Lisp program to parse this outline lines-of-text.
And output it with proper indenting. Output for (print-tree 4)

Will update this post as soon as I've made an interactive version of this
tree, which I consider of great value maintaining an overview text's
structure.
